SULKY-PLOW.

SPECTFICATION forming part of Letters Patent No. 257,327, dated May 2, 1882.

Application filed February 14, 1882. (No model.)

To all whom it may concern Be it known that I, JOHN I. HOKE, of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Sulky-Plows and I do hereby declare that thefollowin g isa full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form: part of this specification, in which- Figures 1 and 2 are reverse side elevations. Fig. 3 is a rear view; Fig. 4, a view of the camlever; Fig. 5, a view of the sliding axle, and Fig. 6 a view of the stirrup.

This invention relates to improvements on sulky-plows; and the nature of my invention consists, first,in combining with the short axle of the land-wheel, which is adjustable on one of the arms of the arched axle, a flanged cam having a hand-lever on it, an anti-friction roller, and a lip formed on the adjustable sleeve of the said short axle, as will be hereinafter explained, whereby the attendantcan level the frame, whether the machine be plowing or on a level road second, in a novel method of suspending the plow and the rear part of its beam from a vertically-adjustable bail, in combina- 7 tion with a suspension-stirrup, which is free to travel laterally and to vibrate on said bail,

and a suspension-spring on which the rear part of the plow-beam is sustained, which springis rigidly secured at one end on top of said beam, aswill be hereinafter explained.

The following description of my invention will enable others skilled in the art to understand it.

A A designate two transporting -wheels,

which are applied to an arched axle, B. The

the overhanging lip b the flange c of a cam, D,-

is received and allowed to play longitudinally with respect to the length of the machine. The cum D and its hand-lever D have their fulcrum atf on the left-hand end of the arched axle B. By this combination of devices the driver, while in his sea-ton the machine, can raise or depress the land-side end of the latter, and thus level the axle, whether the machine be plowing or moving on level ground.

It will be seen that by means of the levercam Itake hold of the land-side axle without the interposition of a second lever or link, and hence the expenditure of very little manual power is required on the part of the driver in leveling the machine.

E designates a shortlongitudinal beam,whieh is centrally secured to the arched axle B at its rear end and braced rigidly to this axle by means of the angular frame F, and also by means of a brace, F, which latter extends a short distance back of the landside and has pivoted to it one end of a bail, G. The opposite eud of this bail is pivoted to the angle of a toothed segment, H, secured rigidly to that end of the arched axle bearing the furrowwheel A. A lever, G, which is an upward extension and integral part of the bail G, is used for adjusting this bail up or down. By means of alatch, h, applied to the hand-lever G this lever can be engaged with segment H and the bail held rigidly at any desired height.

Iwill here state that the hand-lever D of cam D is provided with a latch, 6, adapted to engage with a toothed segment, D on the axle B, and to hold the same at any desired height or level.

The front end of the beam E receives vertically through it a swivel furcated pin, j, between the lower ends of which the plow-beam J is pivoted. This attachmentallows theplowbeam, whiclicarries a plow of suitable construction, to receive free lateral and vertical movements. 1 have not represented means for attachingadouble-tree to theplow-beam clevis, as this may be done in a variety of ways, and I make no claim thereto.

K designates a stirrup, through the lower part of which the plow-beam passes loosely just over the plow. This stirrup is twisted, as

shown in Fig. 6, and it is hung from the trans verse part of the bail G" by means of a roller, 70, having a concave periphery. This stirrup K isa-llowed to vibrate laterally and longitudinally and to traverse the bail-rod.

S designates a flat spring, which is rigidly secured at its front end to the plow-beam. The free rear end of this spring crosses a pin, n, which passes through the stirrup over the plowbeam, and when the plow is in operation the spring bears on said pin a, and by the yielding movement allowed the point of the plow will run at an even depth in the soil, notwithstanding the land-side Wheel may travel over inequalities of surface.

The elongated bail G allows the sulky to turn in either direction without disturbing the position of the plow in the ground.

Having described my invention, I claim- 1. In a sulky-plow, the short land-side axle O, constructed with a sleeve, 0, a stud, a, and a lip, b, in combination with the arched axle B, anti-friction roller 0, cam D, its lever D, and a locking device therefor, substantially as and for the purposes described.

2. The combination ofthe sleeve 0, bearing the short axle G, and adjustably applied on the vertical limb of the arched axle, with a lever having aflanged cam on its end adapted to engage with sleeve 0, for leveling the machine, substantially as described.

3. The combination of the pivoted bail, its hand-lever and locking device, the arched axle, the plowbeam pivoted vertically and horizontally at its front end to the sulky-frame, the suspension-stirrup for this beam, adapted to ride on said bail, and the suspension-spring S, having a bearing, n, on the stirrup, substantial] y as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of 5 two witnesses.
